Radial / low flange - safe?

well, we're talking about low-flange here.

low flange 28h 2x rear, low flange 28h radial front

built by someone with 30 years under their belt...

I have a Miche low flange radial laced to DT Swiss 1.1, it's perfectly fine.

Some manufactures void the warranty if a particular hub is built radial. Some (DT Swiss) market their front hubs as radial hubs.

But like I said, all the Miche Primato hubs (low or high flange) I've seen so far on sale build into the front wheels which are on sale are always radial.

ultegra hub with open pro 36h radial. 2 years of abuse and it still hasnt at any point gone out of true by more than 3mm

Any one radially spoked an on one hub?

Yep, Shimano didn't warrant all their hubs if laced up radially (until a couple of years ago).
I had several (front) hubs with radial spokes, never a problem. Appearantly Shimano had enough claims to state that it was not allowed.

current (36 h not sure about the 32) Dura Ace track hubs come with a little note saying "don't fucking radially lace this hub, you hipsters"

despite this, people continue to do so, without any problems. Personally though I would obey the manufacturers.
I have a radially laced front (to an on-one/halo type hub shell) and my other wheels all 3x, there's no fucking difference really, except I feel safer with 3x tied and soldered on the track because they wheel will stay together in a crash.

Yes I built a Mavic CXP22 on a high flange On-One hub 2 years ago. I had to true it once (after taking it off-road!). It belongs to a mate now who uses it every day and it's perfect still.

I rate those On-One hubs.

Got a front Campag low flange hub radially laced to a DP18. All good so far. The guy who owned it before me found it ok too. Easy to keep it true too.

I'll only do straight-pull radial. Anyone else can do whatever the fuck they want. I don't care.

have radial fronts on all my bikes. i find it much easier to true and i like the way it looks. never had any problems with them, but loads with my 3x backs. i think this is more down to my riding technique than the build.

Unless the hub is warranted for radial lacing, a forged hub with a low spoke count (28h) is safest. I have had a couple of radially laced standard Shimano hubs, but never put really high mileages on them.
